Description
Technical field
The present invention relates to the field of medical instrument technology, the sampling device of specifically a kind of histopathology sample.
Background technique
The materials of histopathology sample (hereinafter referred to as sample), refer to acquired in the tissue of monolith or bulk it is representational
Part production pathological section, is used for histopathogenic diagnosis, is a very important link in histopathogenic diagnosis.For big
Can the histopathology sample of block collect the diagnosis extremely pass that representational diseased region is presented to diagnostician for disease
It is important.Currently used conventional method is first to fix the sample of bulk with neutral formalin, and the set time usually requires 24-
72 hours, it is adjusted that (the processing time of entire sample is generally in 3-5 work according to factors such as the sizes, quality, temperature of sample
Make day, it is seen that the length of set time is very important to the influence the time required to completing pathological diagnosis), sample is bigger, fills
Divide the fixed required time longer.After sufficiently fixing, there may be the part of diagnostic value for making by pathologist acquisition
Make pathological section.If not collecting the tissue of diagnostic value for the first time, need to carry out second or even third time acquisition group
It knits, the selection at this acquisition position has apparent empirical and subjectivity.
In the prior art, the materials of pathological tissue specimen be typically all be sliced materials, and sample inside materials simply by
Common extruding materials, not only larger to pathological tissue specimen destruction, the sample of materials also has different degrees of damage；And it is normal
Rule draw sampling using needle tubing, are suitable only for the sample of fluidised form, because needle tubing is generally fixed, gelatinous pathological tissue
Sample is then difficult to completely sample.
